A pipeline is as good as its weakest point. Accordingly, it is not only important that quality pipes and components are used in a piping system, but also the methodology used to join the pipes and other components.
Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself.
Electro Fusion Welding
Electrofusion is a simple method of joining HDPE pipes in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. Prefabricated fittings are used, incorporating an electrical heating coil which melts the plastic of both the fitting and the pipe, causing them to fuse together.
